To be able to communicate and exchange data with other devices a special component is required.
This component in the PC is called a network card.
The information is usually sent and received via a cable by means of voltage.
For stable transmission while connecting different devices so called Ethernet cables are used.
The transmission rate depends on the performance of the network card as well as on the quality of the transmission cable used.

To connect two devices in a network in a flexible and removable way, a special cable is needed – the patch cable.
Patch cables are categorised into different classes for connection purposes.
Depending on the class, a patch cable has a different number of wires with different shieldings.
At least two of the wires are needed for sending the data and another two are needed for receiving the data.
Patch cables that have a higher quality feature up to eight lines.
In this way, they are more effectively shielded from electromagnetic interference.
The classes ( Quality Standards) are indicated as Cat.
Cat 3 10 MBit/s 16MHz
Cat 5 100 MBit/s 100MHz
Cat 5e 1 Gigabit/s 100MHz
FastCat5 5e 1 Gigabit/s 350MHz
Cat 6 1 Gigabit/s 250MHz
Cat 6a 10 Gigabit/s 500MHz
Cat 7 10 Gigabit/s 600MHz
Cat 7a 100 Gigabit/s 1000MHz

The lines for data transmission laid in a building are grouped together at central locations.
The cable ends are collected in a device like a distribution box – the so called patch panel.
The cables are connected on the back of the patch panel.
There are color-coded clamps into which cable ends of the Cat standard can usually be pressed in.
On the front side, there is a RJ45 socket for each of the data cables.
The RJ45 sockets are used to connect the incoming data cables to devices such as switches or other patch panels.
This makes it easy to create flexible assignments between end devices within networks.
Since patch panels are often installed in server racks, the size of the panels is usually specified in inches and HE.

Networks for data transmission are present in every company and are used for communication between different end devices.
Especially in the environment of IoT, the existing data network receives an additional benefit through the use of PoE devices.
POE stands for Power over Ethernet. In addition to data transmission, the power supply of end devices is also realised by using an eight-core Ethernet cable. The power supply is provided by appropriate switches to which the end devices (e.g. infrared cameras) are directly connected via Ethernet.
The main advantage results from the elimination of a separate power supply for the respective end device and the thus reduced installation costs.
It should be noted that POE can usually only be used for network devices that require low power. These are e.g. IP telephones, small servers, cameras, etc.

A network switch that combines the functions of a conventional switch with the option of supplying connected devices with power via the Ethernet cable is called a PoE switch.
PoE stands for Power-over-Ethernet. This technology enables data transmission and power supply to PoE-capable end devices, such as VoIP telephones and surveillance cameras, via the RJ45 network cable.
The advantages are the cost savings for the installation of power and network cables in locations without sockets, as well as the reliability due to a constant power supply (when using a UPS).
In addition, managed PoE switches offer the ability to remotely restart connected devices, reducing downtime.
PoE switches can typically deliver power from 15 watts (PoE) up to 90 watts (PoE++) per port. It is important to note that the actual power a switch can deliver depends on several factors, including the number of PoE devices connected and the overall capacity of the switch. It is advisable to check the specifications of the PoE switch in question to determine the exact power per port.
